posts or poles, more particularly telephone,

telegraph, electric light or similar poles, and it has for its object toprovide a construction on able of withstanding the destructive e ects ofmoisture and the elements and which shall be strong and durable for thepurpose intended.

The invention consists of a cement or concrete base set in the earth androjecting above the surface thereof to provit ea pedestal, combined withan upper pole of wood or other material, with strengthening or anchoringrods embedded in the concrete base and connected with the pole to firmlyanchor it to said base, with an additional surrounding covering, asshall be more fully hereinafter described.

Referring to the drawings: Figure 1 is a view in elevation of the baseportion and a portion of the attached pole, portions of some of theanchoring rods being exposed. Fig. 2 is a vertical sectional view ofFig. 1. Figs. 3 and 4 are cross sectional views on the lines III. III.and 1V. IV. of F-igsl and 2 res eetively. Fig 5 is a sectional detailview i ustrating the use of a tightening wedge.

In the drawings, 2 represents the base of concrete or cement set withina receiving hole in the ground around an annularly arranged series ofvertical anchoring rods 3, of steel or iron, of any suitable form adated to make holding engagement with the ase 2. Said base is continuedupwardly beyond the ground level as indicated at 2 for any desireddistance, withina suitable removable forming mold, and finished oilreferably with a flat top 4 and beveled e ges 5, although any othersuitable form may be given to the top of the. base to adapt it toreceive. the pole 6. The particular advantage of the bevel 5 is that thelower edge of the shell 9 more tightly embraces the base 2. Theanchoring rods 3 are extended u wardly through and beyond the upper enof the base 2' as shown at 7 for a suitable distance and terminate inany suitable form for attachment to the pole as inwardly turned ti sorextrcmities S.

trennties 8 are driven into the )ole as shown in Figs. 1 and 2 oreonnecte. to it in any other suitable manner, thereby firmly connectingthe pole and base together.

An outer covering 9 of concrete or cement is then formed around theholdim ends of the anchoring rods, firmly embedding them, embracing thebase of the pole, and etl'ectus ally connecting it within a permanentup-.

wardly extending concrete shell to the main base. Said outer coveringmay conveniently be molded withm any slut-able outer mold 'hen the pole6 is firm y. set upon the top of the concrete base, the ex-j PatentedFeb. 4, 1908.

or shell and preferably tapers upwardly asshown,.giving a good tinis leda pearance.

When desired, the pole 6 may )0 tightened or adjusted to vertical or anydesired inclined position bythe insertion of wedges 10 between thebottom of the pole and top of the r base 2' as shown in Fig. 5, thetension of the rod terminals 7 being thereby increased and absorbing allintervening clearance. By

such means the pole maybe rigidly set upon v the base in the desiredposition and fixedly attached thereto before application of thesurrounding shell 9. Fig. 5 also shows at the left side one of theanchoring rod terminals 9 in its original position before being driveninto the pole. i

The advantages of my invention will be 1 readily a preciated by al hosefamiliar with the use 0 poles.

Ordinarily wooden poles set directl into the ground became decayed atthe sur ace of the ground when exposed to the destructive effect of theelements, and their life and efficiency is thus proportionally reduced.

By my invention the base of the wooden pole, being entirely above theground and protected by the inclosing shell 9, is not sub- 7 Ject todeterioration, while the renewal of posts due to breakage or otherinjury is rendered easy and cheap by merely removi the shell 9,disconnecting terminals 7 an inserting a new post.

Likewise, old posts may becut ofl' above ground and then mount ed onconcrete bases without sacrificing any of their necessarv height.

The number, orm and arrangement of the anchoring rods is within theogment of the builder, and 1 preferably maire the terminals 7 of varyinglength as shown in Figs. 1 and thus staggerim their points of eetachmento the pole, to insure the best results.

g l l Other changes or variations may he made by the skilled mechanicwithout departing from the scope of the following claims:
